HEAT-RADIATO R.

SPECIFICATION forming part of Letters Patent No. 357,207, dated February 8, 1887.

Application filed April 7, 1886. Serial No. $8,154. (No model.)

To all whom it may concern:

Be it known that I, J AOOB FRANTZ KEENER, a citizen of the United States, residing at Kittanning, in the county of Armstrong and State of Pennsylvania, have invented a new and useful Improvement in Heatltadiators, of which the following is a specification.

My invention relates to an improvement in heat-radiators; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and

. will not be placed on the pipesB G. On the outer side of the drum, near thelower end thereof, is a hinged door, D, and the opening in the lower side of the drum covered by the said door, when the latter is' closed, is covered by a wire-netting, E. In the upper end of the drum is arranged a vertically-movable slidedamper, F, which is adapted to partly cut off the inner end of the discharge-opening O.

In operation the pipes O and B enter the side of the chimney in an upper apartment and communicate with the flue in the chimney, and in the latter,-above the pipe B, is located a damper, G. When this damper is closed, the heat which passes up the chimney is deflected and caused to pass into the drum through the pipe B. If the door.D is closed and the damper F is opened, (the damper G remaining closed,) theheated air from the chimneyflue will pass upwardly through the drum and through the pipe 0 back into the chimney, and a small degree of heat will be radiated from the drum intp the room. If the damper F is partly or entirely closed, so as to obstruct the escape of the heated air from the drum to the chimney, (the damper G remaining closed, as before,) the drum will become heated to a higher degree than in the previous instance, and will consequently radiate more heat into the room. If the door D is then opened, (the'dampers F and G still remaining closed,) the heated air from the chimney will be admitted into the room'through the screen E,and the drum then serves as a register, and is working at its maximum degree of efficiency as a heater.

If it be desired to employ the device as a ventilator for the apartment, this may be accomplished by opening the damper G in the chimney-flue,to prevent thedeflection ofheated air from the chimney to the drum, and the door D and the damper F must be also opened, when the air in the apartment will enter the drum through the screen E and escape through the pipe 0 up into the chimney.

The screen is useful to prevent soot and other products of combustion from escaping into the room from the drum when the latter is used as a register.

A heat-radiator thus constructed is cheap and simple, is not likely to get out of order, and will be found very efficient in localities where natural gasis used as fuel, enabling upper apartments to be heated by the waste heat which usually escapes up the chimney.

In experiments made with a heat-radiator thus constructed, in practical operation, I obtained a greater degree of heat in an upper apartment in which the radiator was located than was thrown out by the fire in the room below.

Having thus described my invention, I

claim- 1. The combination, with a chimney or line having the damper G to. open enclose the same, of the drum A, having the pipeB at its lower end communicating with the flue below the damper G, the pipe 0 at its upper end communicating with the flue above the damper therein, the damper F, to open or close the pipe 0, and the opening in the lower portion of the drum having the screen E and the door D, for the purpose set forth, substantially as described.

2. In combination with brackets attached to the flue, the heat-radiator supported on the brackets above the floor, and pipes B 0, communicating with .the radiator and opening into the chimney or flue, and a damper, G, 10- opening, and a door, D, to close over the cov cated in the chimney or flue between the pipes ering, as set forth.

B O, as set forth. In testimony that I claim the foregoing as 3. A heatradiator consisting of a hollow my own I have hereto affixed my signature 5 reservoir provided at the upper and lower in presence of two witnesses.
